Transmission Repair and Maintenance Services for Diesel Trucks

At Fleet Master Truck & Trailer Repair, we recognize that the transmission is a critical component of any diesel truck. A well-maintained transmission ensures smooth and efficient gear shifting, prolonging the lifespan of your vehicle and reducing the risk of costly breakdowns. Our technicians are trained to perform a wide range of transmission services, including:

  • Transmission diagnostics and inspections
  • Transmission fluid change and filter replacement
  • Clutch adjustment and replacement
  • Transmission rebuilds and replacements
  • Repair and replacement of transmission components, such as bearings, gears, and synchronizers

We utilize state-of-the-art diagnostic equipment to identify and repair transmission issues in your diesel truck accurately. Whether you have a manual or automatic transmission, our technicians have the expertise to service and repair it.

Transmission Rebuild Services at Fleet Master Truck & Trailer Repair

In addition to standard repair work, we specialize in full transmission rebuilds for heavy-duty diesel trucks and fleet equipment. Transmission rebuilds are often the most cost-effective solution when internal wear, overheating, slipping, delayed engagement, or harsh shifting begins to compromise reliability. Our rebuild process includes complete teardown, inspection, and replacement of worn internal components to restore proper shift performance and load-handling strength.

Transmission rebuild services may include:

  • Replacement of clutch packs, steels, seals, and gaskets
  • Torque converter inspection and replacement if needed
  • Valve body servicing and solenoid testing
  • Bearing, bushing, and gear replacement
  • Endplay measurement and internal clearance checks
  • Final road test and performance validation

Differential Rebuild and Drivetrain Repair Services

Your differential is responsible for transferring power from the driveshaft to the wheels while allowing proper wheel speed variation during turns. When differential issues occur, they can quickly lead to driveline failure, wheel-end damage, and major downtime.

Fleet Master Truck & Trailer Repair offers comprehensive differential rebuild services designed to restore strength, quiet operation, and long-term performance. If you’re experiencing whining, grinding, clunking, vibration under acceleration, or metal contamination in gear oil, your truck may require a differential rebuild before a catastrophic failure occurs.

Our differential rebuild and repair services include:

  • Ring and pinion gear replacement and setup
  • Bearing and seal replacement
  • Carrier inspection and rebuild
  • Backlash and gear pattern adjustment
  • Lubrication system inspection and fluid replacement
  • Axle shaft and yoke inspection

Proper differential setup is precision work, incorrect pinion depth, backlash, or preload can cause rapid gear wear. Our technicians use the correct measurements, specifications, and tooling to ensure your differential operates reliably under heavy-duty service conditions.

Clutch Repair and Maintenance Services for Diesel Trucks and Fleets

Clutches are essential components in manual transmission vehicles that transfer power from the engine to the transmission; they’re equally important in those vehicles with automatic transmissions, even if the user doesn’t have to engage and disengage it. A properly functioning clutch is crucial to the overall performance of your diesel truck. Our technicians at Fleet Master Truck & Trailer Repair offer comprehensive clutch repair and maintenance services, including

  • Clutch inspection and diagnostics
  • Clutch replacement and repair
  • Flywheel resurfacing and replacement
  • Hydraulic system repair and maintenance
  • Clutch cable and linkage adjustment and replacement

Our team is well-versed in the specific needs of diesel trucks and can provide tailored solutions to ensure that your vehicle's clutch system remains in top condition.
